Abstract: An apparatus for a cellular communications network including a broadband transceiver for providing upconversion and downconversion between an RF band-of-interest and an intermediate frequency (IF); a transmultiplexer (XMUX) interfacing with the transceiver. The XMUX demultiplexes a single wideband IF receive signal to form a set of individual frequency channels on a receive path of the transceiver, and multiplexes the frequency channels into a single wideband IF transmit signal on a transmit path. The BBS also includes a rate converter processor (RCP) that interfaces with the XMUX for converting at least one of the frequency channels from a first data rate of the XMUX to a second data rate, and a communications bus that transports the modulated IF signals for each of the frequency channels between the RCP and a plurality of channel processors (CP). Each CP processes any of a plurality of traffic channels contained on any of said IF signals. An alternative architecture for the apparatus is disclosed.

Abstract: En måleinnretning er gitt som bestemmer væskeegenskaper fra vibrasjonsfrekvenser i et prøvehulrom. I en utførelse inkluderer måleinnretningen et prøvestrømningsrør, vibrasjonskilde og detektor montert på røret, og en målemodul. Prøvestrømningsrøret mottar en strøm av en prøvevæske for karakterisering. Målemodulen anvender vibrasjonskilden til å generere vibrasjoner i røret. Målemodulen kombinerer signalene fra vibrasjonsdetektoren på røret for å bestemme egenskapene til prøvevæsken slik som tetthet, viskositet, sammentrykkbarhet, vannandel og boblestørrelse. Målemodulen kan videre detektere visse strømningsmønstre slik som strømningsplugg, for eksempel. Fora måle prøvevæsketettheten, bestemmer målemodulen resonansfrekvensen til prøvestrømningsrøret. Tettheten kan så bli beregnet i henhold til en formel som kompenserer for temperatur og trykk i systemet. Andre væskeegenskaper kan bli bestemt fra prøverørets resonanstoppamplitude, toppbredde og/eller toppform. Variasjon i tetthetsmålingene kan bli brukt til å detektere og karakterisere multiple fasevæskestrømninger. Bruken av vibrasjonskilde og detektor er anordnet på en måte som sterkt forbedrer nøyaktigheten og påliteligheten til måleinnretningen over et område av temperaturer, trykk og sjokkakselerasjoner slik som de man kan finne nedhulls i en brønn.
